In the previous article introduced the principle of HashMap, this section is the last section of Concurrentmap, so will be a complete introduction of CONCURRENTHASHMAP implementation.Concurrenthashmap principleA method of implementing a map with a

As you can see in the class diagram in the "Introduction to concurrent container Part 4 concurrent Queue and queue" section, Blockingqueue is the primary thread-safe version for queue. This is a blocking version, which allows the Add/remove element

The previous chapters mainly talk about atomic operations, as far as the questions related to atomic manipulation or traps are put in the final summary. This chapter begins with a small amount of space to talk about locking mechanisms.The lock

Prior to JDK 5, the Java language was guaranteed to be synchronized by the Synchronized keyword, which would result in a lock (later chapters will also talk about locks).The lock mechanism has the following issues:(1) Under the multi-thread

If Countdownlatch is a one-off, then cyclicbarrier just can be recycled. It allows a group of threads to wait for each other until a common barrier point (common barrier points) is reached. The so-called barrier point is the time when a set of

Common Concurrency trap volatileVolatile can only emphasize the visibility of data and does not guarantee atomic operations and thread safety, so volatile is not a panacea. Re-ordering of reference instructionsVolatile is most commonly found in the

From this section, formally enter the part of the thread pool. In fact, the whole system has been dragged for a long time, so the later chapters will speed up, or even just a semi-finished or simplified, later time to supplement and perfect.In fact,

We know that threads have multiple execution states, and the thread pool that manages threads also has multiple states. The JVM exits after all threads (non-background daemon threads) terminate, and it is important to close a thread pool in order to

There was no update for some time. Then go on with the last verse.Queue in addition to the implementation described earlier, there is a two-way queue implementation deque. This queue allows queues to be queued at the head and tail of the queue, so

There is a sorted set in set SortedSet, which is used to hold objects arranged in a natural order. A FIFO model that supports sequencing is also introduced in the queue.Introduction to the concurrent queue and queue describes that Priorityqueue and

Garbage collectorI personally call it the "function to block the garbage collector" or "a function that has access to another function's internal variables" (of course, this is my own way of understanding, everyone may have different ways of

Chapter One: Spring data JPA   What is spring data is an open-source framework for simplifying database access and supporting cloud services. Its main goal is to make access to data easy and fast, and to support map-reduce framework and cloud

VMware's three networking models are bridge,nat,host-only. VMware believes that the use of these three networking modes can build any network topology, and indeed it is. If you are proficient in the network, it should be easy to understand the

Before learning about the variable scope of JavaScript, we should make a few clear points: The variable scope of JavaScript is based on its unique scope chain. JavaScript does not have block-level scopes. Gambling King Casino

Node service based on non-blocking, event-driven, has the advantage of low memory consumption, and is very suitable for processing massive network requests.V8 garbage collection mechanism and memory limitJavaScript is similar to Java, with the

Originally wanted to be more comprehensive and in-depth talk about Concurrenthashmap, found online there are a lot of hashmap and concurrenthashmap analysis of the article, so this section as far as possible to analyze the details, less theoretical
